Testing with Files and directories in JUnit is easy thanks to TemporaryFolder@Rule.
In JUnit rules (@Rule) can be used as an alternative or an addition to fixture setup and
cleanup methods (org.junit.Before, org.junit.After, org.junit.BeforeClass, and org.junit.AfterClass), but they are more powerful, and can be more easily shared between projects and classes.

In my previous blog post I showed how easy Jersey can be configured with Spring Boot. My exploration on Spring Boot and Jersey did not end and I investigated the possibility of using Spring HATEOAS along with Jersey in Spring Boot application. Spring HATEOS allows creating REST representations that follow the HATEOAS principle and (as of writing this article) has basic JAX-RS support for working with links. In this blog post I will share some examples of how I integrated Spring HATEOAS with Jersey in a Spring Boot application.

Along many new features, Spring Boot 1.2 brings Jersey support. This is great step to attract those developers who like the standard approach as they can now build RESTful APIs using JAX-RS specification and easily deploy it to Tomcat or any other Spring’s Boot supported container. Jersey with Spring platform can play an important role in the development of mico services. In this article I will demonstrate how one can quickly build an application using Spring Boot (including: Spring Data, Spring Test, Spring Security) and Jersey.
